Staff Backend Engineer

Requirements:

• Strong proficiency in Python as the primary language.
• Solid grasp of system design, API design, SQL and vector databases, and cloud infrastructure.

Production LLM Experience (2+ Years):

• Built and shipped real production systems using LLMs, RAG pipelines, agents, embeddings, evals, or fine-tuning.
• Understands the limits of models, not just the hype. Can clearly articulate the difference between RAG and fine-tuning and when to use each.

Independent Ownership:

• Can take a vague problem, define the solution, build it, and measure its impact without hand-holding.
• Track record of shipping autonomously and iterating based on real user/business feedback.

Domain-Diving Instinct:

• Willingness and ability to learn the business domain (marketing, SEO, geo, content) deeply enough to make smart product calls.
• This is the rarest trait we screen for engineers who understand the why behind what they build.

Business-First Thinking:

• Consistently connects engineering decisions to user outcomes, revenue impact, and retention metrics.
• Asks, "Does this move the needle for customers? " before optimizing for technical elegance.
